Sen. Rand Paul released 1,141 pages of Dr. Anthony Fauci's private pandemic diary on July 27, 2026, spread across 11 government servers. The notes run from December 2019 through December 2022 and document Fauci's private thinking through the early days of COVID-19 — including a February 1, 2020 call where he recorded that 9 to 10 of 11 to 12 scientists believed the furin cleavage site in the virus could have been deliberately inserted. Paul subpoenaed Fauci to testify before the Senate Homeland Security Committee on Wednesday, July 29, at 10am ET.

1. The Diary Proves a Cover-Up (Sen. Rand Paul, R-KY)

Paul says Fauci privately knew the lab-leak theory was credible, then helped bury it.

His diary directly contradicts what he said at the podium. On January 31, 2020, Fauci noted that scientists raised the possibility the virus could have been "deliberately inserted and either accidentally released or deliberately released." By April 2020, he was telling the country at White House briefings that mutations were "totally consistent with a jump of a species from an animal to a human."

He helped draft the paper he later cited as independent science. Documents released before this diary showed he had a hand in writing the "Proximal Origin" paper — the study that declared no laboratory scenario was plausible — submitted just four days after the February 1 call where most scientists thought the opposite.

The questions Paul plans to ask Wednesday are blunt. Did Fauci fund gain-of-function research while telling Congress he didn't? Why were records destroyed? And why did he need a presidential pardon from Biden in January 2025?

2. But the Diary Shows Normal Science (Dr. Anthony Fauci, former NIAID Director)

Fauci and his defenders say early private uncertainty is how science works — not evidence of a cover-up.

Scientists had almost no data when the February 1 call took place. Virologists who have reviewed the diary's context note that the meeting happened in the first days of a novel outbreak, when the genome was barely sequenced. Raising possibilities — including unlikely ones — is what early crisis science looks like.

Public guidance tracked the best available evidence at each point. Fauci has publicly stated he has an "open mind" on the virus's origins and explained that as the science evolved, so did the guidance. His position is that his statements reflected what scientists understood at each moment in time.

Congressional investigators found grant problems, not a cover-up. Years of hearings "turned up embarrassing emails and problems with grants, but evidence of a larger cover-up is lacking." The presidential pardon, defenders argue, was a precaution against politically motivated prosecution — not an admission of guilt.

3. Either Way, the System Failed (House COVID Select Subcommittee, Bipartisan)

NIH funded overseas research for years with no meaningful oversight guardrails.

NIH was funding overseas research with no meaningful guardrails. Grants to EcoHealth Alliance funded research at the Wuhan Institute of Virology, and Fauci's diary documents his private defensiveness about those questions — regardless of how the cover-up debate resolves.

Both parties agreed on what needs to change. The House COVID Select Subcommittee's final report — a two-year, 500-page investigation — identified five bipartisan points of consensus and found the virus "almost certainly" came from a lab. The recommendations focused on gain-of-function oversight reform and better rules for scientific communication.

The problem goes deeper than Fauci. Rep. Brad Wenstrup (R-OH) and Democrats on the committee agreed that scientific institutions need clearer rules for what happens when private scientific uncertainty diverges from public health messaging. That fight will outlast Wednesday's testimony.

Where This Lands

Paul's camp argues the diary makes it impossible to claim Fauci's public confidence was scientifically honest — his own notes say most scientists privately thought the opposite. Fauci and his defenders say the diary is being cherry-picked to misrepresent how crisis science actually works. The bipartisan reform camp has already moved past the personal culpability debate and published structural recommendations. The diary has set the terms. Fauci testifies Wednesday.
